TRACK-SANDING- DEVICE.

Application filed October 3, 1908.

To all whom "it may concern:

Be it known that I, THOMAS N. LOCKE, a citizen of the United States,residing at Salem, in the county of Essex and State of Massachusetts,have invented new and use-: ful Improvements in Track-Sanding De-;

attached, a predetermined charge of sand.

will be distributed upon the track at a point immediately in front ofthe wheels of the car trucks.

A still further object of my invention resides broadly in the provisionof a hopper adapted to contain a quantity of sand for distribution, andto locate beneath the said hopper a revoluble track engaging element orwheel for receiving sand from the hopper and discharging it upon thesurface of the track as above described, and to further provide a novelform of agitator located within the hopper and adapted to be actuatedupon rotary movement of the said element or wheel.

Another object of my invention is to provide a device of the classdescribed. which will be provided with means whereby it may be attachedtoa car truck or to any other part of the car, and to further providesimple, effective and novel means for re.- taining the distributingwheel upon the track upon which it is to travel.

Other objects and advantages will be apparent as the nature of theinvention is better set forth, and it will be understood that changeswithin the scope oftheclaims may be resorted to without departing fromthe spirit of the invention.

furcated horizontally at 2 and 3 for a purpose to be hereinafterexplained. The head member -or block 1 is provided with a bracket 4 ofyoke form which is preferably provided with a pair of horizontallydisposed arms 5 adapted, in any suitable manner to be connected to thetruck of a car or to any other desirable part thereof. A frame 6 isprovided and is formed with a head or bearing 7 mounted in thebifurcated portion 3 of the head member or block and as illustrated theblock or head memberhas connected thereto a vertically disposed pivotpost or pintle 8 which is connected with the head 7 of the frame 6 sothat the latter is free for, slight oscillatory movement. At the rearend the frame 6 is provided with a slot 9 in which is disposed a portionof a sand distributing element or wheel 10. The said distributingelement or Wheel 10 is preferably revolubly mounted upon a shaft 11journaled at its ends in bearing boxes '12 which extend downwardly fromthe frame 6. The said distributing element or wheel 10 consists of a vpair of spaced annular flanges or collars 13 and 14, the peripheralfaces of which being arranged to travel upon the tread surface of a railA. The said collars or flanges 13 and 14 are connected to each other bymeans of may be arranged to distribute upon the surface of the track, apredetermined charge of sand or the like. The collar or flange 14 isformed with a peripheral annular extension 17 which serves as a guideflange for the distributing wheel and eflectively holds thesame initsoperative position upon the rail as will be readily understood.

, The frame 6 just described will be re ferred to hereinafter for thepurpose of clearness as a main frame, and disposed immediately above thesaid main frame and in suitable spaced relation thereto preferably, is asupplemental frame 1.8 which has its forward extremity. operativelyconnected with the postor pintle 8 so that the frame is free for slightoscillatory movement. supplemental frame 18 is provided adj aoent to itsrear end with an elongated slot 19 disposed immediately in line withtheslot 9 in the frame 6. A hopper 20 is carried by The the main frame andits lower reduced end extends downwardly below the slot 19 and ispositioned immediately above the distributing element or wheel 10. Thefront and rear walls 21 of the said hopper have secured thereto bolts orsuitable adjusting and clamping devices 22, the shanks of the said boltsor devices being disposed in elongated slots 23 formed in plates 24mounted within the hopper. In View of the just described construction itwill be apparent that the plates 24 are mounted for angular adjustmentwithin the hopper so that the discharge end thereof can be reduced orenlarged at'the will of the operator so that the desired quantity ofsand can be delivered from the hopper to the distributing element. Theplates 24 in width are somewhat less than the distance between theflanges or collars 13 and 14 and the said plates have their lowerextremities partly disposed in the said space between the flanges orcollars.

The main frame has connected thereto in any suitable manner at a pointpreferably at the'rear of the hopper a post or standard 25 havingpivoted thereto at its upper end a bracket 26. The bracket 26 carriesspaced depending abutments or fingers 27 and- 28,; the latter having itslower extremity adapt- 1 ed for engagement with the rear extremity? ofthe supplemental frame, and the former has its lower extremity normallyengaged with a stop or lug 29 which extends prefer- 5 times be held inits operative position, the

main frame. the bolts are extended through passages in the supplementalframe. As shown, the bolts are provided with washers K which are seateddirectly against the main frame to close the recesses in which theheaded portions of the bolts are seated. Springs 32 are mounted upon thebolts and are confined between the washers and the adjusting nuts 31.Nuts 31 are also adj ustably mounted on the bolts and are disposed abovethe nuts 31 and they bear beneath the supplemental frame. On downwardadjustment of the nuts 31 the bolts will be elevated slightly so as tocause the nuts 31 to be moved tightly against the supplemental frame,thus forcing the same against the finger 28. This construction isnecessary in order that the device can be made to accommodate itself totracks of different character or to one in which there may be certainimperfections, it being understood that it is essential that the wheel10 or sand-distributing element is forced to bear against the track toinsure a proper discharge thereto of the sand.

Arcuate guards 33 are carried by the main frame and extend partly aroundthe dis tributing element and serve as means for obviating the prematuredlscharge of sand.

The hopper has mounted therein an oscilla- I tory shaft 34 which carriesa plurality of downwardly extending tines or agitating fingers 35, thesaid fingers being disposed in suitable spaced relation to each otherand extend crosswise of the machine approximately the width of thehopper. The shaft 34 has connected thereto at one end a crank arm 36with which is connected one end of a pitman or connecting rod 37operatively connected with the distributing wheel as clearly shown inFig. 1.

The head member or block 1 is provided with a horizontally disposed gearsegment 38, the teeth of which meshing with those of a gear segment 39pivotally mounted upon the main frame forwardly of the hereinbeforedescribed hopper. The segment 39 has secured thereto a horizontallydisposed arm 40, the ends of the said arm being secured to the forwardextremities of helical springs 41. The rear extremities of the saidsprings are secured in any suitable manner to brackets 42 which extendupwardly from the sides of the main frame. Incident to the fact that themain frame is mounted to the head or block 1 so that it can be moved Ihorizontally, it will be appreciated that through the medium of the gearsegments 38 and 39 and the springs 41 which are connected thereto, themain frame will at all automatically fed to the distributing ele- -mentor wheel 10. The pockets 16 formed in the distributing element conveythe desired quantity of sand to the track and discharge it immediatelyin front of the wheels of the car trucks. It will be apparent that I mayadj List the plates 24 to determine the desired discharge of sand fromthe hopper to the distributing wheel. v

A device of the'character described is extremely simple in construction,may be applied to cars of the well known type and is automaticallydriven by reason of the fact thatit is carried directly by the car andthat the distributing wheel rides upon one of the rails. The operationof the distributing wheel not only discharges upon the track the desiredquantity of sand, but through the connections her-einbeforedescribedbetween the oscillatory shaft 34 and the said distributingwheel, it is obvious that the 1 agitating fingers will be operatedsimulta- Copies of this patent may be obtained for neously with theoperation of the-wheel so that sand within the'hopper will be thoroughlyloosened whereby it may be properly discharged to the distributingwheel.

I claim;
